概括

用β-素 (β-CN) 强化婴儿配方剂可加速消化,并增强小鼠幼中生物活性的释放. 这表明,与标准配方相比,婴儿的营养益处更好.

科学领域:

营养科学营养科学
生物化学生化学
儿童营养学儿童营养学

背景情况:

β-素 (β-CN) 是母乳中的主要蛋白质,但在婴儿配方奶粉 (IMF) 中不那么丰富.
对于β-CN强化对婴儿消化和生物活性生成的体内影响尚不清楚.

研究的目的:

在新生小鼠模型中,研究牛奶蛋白中β-CN强化对消化特征和生物活性释放的影响.
为了比较普通β-CN含量 (OBCN) 与强化β-CN含量 (FBCN) 牛奶蛋白溶液的影响.

主要方法:

哺乳老鼠幼被用OBCN或FBCN牛奶蛋白溶液进行了采集.
分析了胃排空速率,蛋白质分解效率和肠道消化物的形状.

主要成果:

与OBCN组相比,FBCN组显示了显著加速的胃排空和增强的蛋白质分解效率.
消费FBCN导致小肠中的多样性更大,包括更丰富的生物活性候选人,具有更广泛的功能谱.

结论:

牛奶蛋白中的β-CN强化对新生儿的消化过程产生了积极的影响.
增加的β-CN水平增强了各种生物活性的释放,这表明IMF的潜在健康益处.

Protein Digestion

Protein Digestion

Protein digestion begins in the stomach, where the highly acidic environment can easily disrupt protein structure by exposing the peptide bonds of polypeptide chains. After polypeptide chains are broken into individual amino acids by a series of digestive enzymes, the amino acids are transported to the liver via the bloodstream to produce energy.

Hormonal Regulation

Hormonal Regulation

Hormones regulate a significant portion of digestion through activation of the neuroendocrine system. The neuroendocrine system of digestion contains many different hormones all with multiple functions that are both, directly and indirectly, involved in digestion.
